Add "create callback" functionality for Commerce Authorize.net

This patch works if its your first card you are adding that has a unique description. If you add the same description for a different card it fails. If you delete one card and add a new card under the same description it fails.

I have updated the create hook to either create the whole profile or if it exists then add to the existing profile id. I haven't done a patch only provide code for review.

#1812740: Give user the ability to add a card on file BEFORE checkout is now in the 2.x branch of Commerce Card on File. The patch should probably be rewritten to depend on that.

Actually, after reviewing what really went into the 2.x branch, it doesn't look like the code this patch depends on made the cut.
